Description: The poster is a collage of several black and white images that surround a central image. The central image around which all of these vignettes are arranged depicts an heraldic shield that has five red stars on a black stripe. The image below this shield is of the Concord Minute Man statue.

Description: All-lettered poster in black & white. Text of the Atlantic Charter of August 14, 1941, signed by Franklin D. Roosevelt and Winston Churchill. Title and heading at top. Two columns of text below in italics.

Description: Black and white drawing. A caricatured Japanese soldier holding a smoking gun stands over a fallen man labeled "U.S. pilot". In the distance is a pagoda. At right is a large shadow of a man's head and and shoulders, which appears to be descending over the Japanese soldier. He wears a miner's helmet and the words "more metal for U.S. planes, tanks, guns" appear on his shadow.

Description: Color poster of a battle scene. A soldier lies on the ground and holds his military rifle in a ready position. Several parachutes can be seen the sky above and descending around the soldier.

Description: The main part of the poster is a large black-and white photograph of the faces of a smiling teenage girl and boy. The lower part of the poster is a green-tinted photograph of young volunteers harvesting potatoes. A farmer on a mule- or horse-drawn farm machine can be seen in the background. The sky in the background is colored blue.

Description: Although a number of investigations of the bearing strength of aluminum alloys have been made, the problem remains one of considerable interest to the aircraft industry. For this reason it has seemed advisable to make additional tests of the commonly used aircraft alloys in an effort to establish a better basis for the selection of allowable bearing values. Current design practice does not recognize the effect of edge distance upon bearing strengths, and for this reason edge distance was one of the principal variables considered in this investigation. The increasing emphasis being placed upon permanent set limitations makes it essential that more information on bearing yield phenomena be obtained. The object of this investigation was to determine bearing yield and ultimate strengths of the following aluminum alloy products: 17S-T, 24S-T, Alclad 24S-T, 24S-RT, 52S-0, 52S-1/2H, 52S-H, 53S-T, and 61S-T extrusions. Ratios of these bearing properties to tensile properties were also determined.

Description: Bearing tests of AM-3S, AM-52S, and AM-C57S magnesium-alloy sheet in various thicknesses and tempers were made. Bearing yield and ultimate strengths were determined and compared for various edge distances and for various ratios of loading-pin diameter to sheet thickness. Tensile strengths were determined and ratios of average bearing yield and ultimate strength to tensile strength are given. The results of the tests indicated that ultimate bearing strengths increased with edge distances up to 1.5 to 2 times the diameter of the loading pin; that ultimate bearing strengths are a function of the ratio of pin diameter to sheet thickness; and that these properties are effected only slightly by increases in edge distance greater than 1.5 diameters.
